  1. Yes, the aileron pot has wires which move, i am guessing that something became dislodged possibly when i recently dropped the tranny on its sticks. On the positive side, i learned a lot investigating the problem. Thanks to all for the advice, it steered me where i needed to go

     

    Have also realised that the t6k isnt the highest quality transmitter 😞

  2. Stkadj is on page 166 of manual, tried everything mentioned, all ok, transmitter fine until now

     

    took the back off and had a fiddle, pressed the plugs in on the gimbal and voila! Now working perfectly with 100% movement restored. Conclusion, bad connection, which is still a concern but does all seem to be back to normal

  3. Hello

     

    spent an hour trying to figure out why aileron servos throw is half it should be? Using two mini 4-max servo’s for ailerons and standard 4-max for other controls. Strangely the aileron throw is not what it should be. The servo function on the trans shows each servos throw/position and its ver clear. Tried boosting their movement using the rates/exp page (up to 140%) which helps but im missing something?

     

    any ideas pls?

     

    thanks

  4. To reiterate, its not a shrader valve, its just the same outside diameter, it has no internal valve whatsoever nor thread to hold one etc. its categorically not a non return valve. 
     

    my assumption is the blue t pieces branded “spark” must be non return valves and i wondered if anyone had seen this before?

     

    pumped it up earlier and its holding air and now no air is leaking out of the fill valve now which is odd. 
     

    anyway, restrictors have arrived and i plan to fit these ahead of the legs to slow the operation speed and stop the slamming. I will then connect it all up again, pump it up to pressure and go for another test

  5. Thanks for all the good advice which is taken. Im still a bit puzzles as to where the dill non return valve is since the fill valve definitely has nothing inside, just an adaptor to allow a shrader valve to attach to the airline?

     

    Anyway, have now ordered a non return fill valve since it cant so any harm. 

  6. Hello

     

    Finishing an old topgun? Spitfire artf and it came with air retracts which i

    dont seem to be getting on with.

     

    Firstly one of the legs was sticking, eventually fixed. Now when i pump air in via the fill valve its slowly leaking out again via the fill valve (can hear it hissing).  They slam up and down so have ordered some delay couplings from MSL’s, hopefully they will help
     

    Question, where is the non return valve that stops the air escaping? The fill valve doesnt appear to be non return which is confusing? There is a blue three way adaptor after the fill valve that connects the reservoir to the fill valve and the switch body, im guessing it must be that? If so, surprised its leaking

     

    Think i have the valve switch servo movement correct adjusted, goes to circlip on both ends

     

    all advice welcomed, thks

  7. Having recently battled with a barely used asp 90 fs and had troubles with idling, bearings and compression i switched to a similar os 90 fs which was immediately perfect. I have now had a few asp engines and all seem to have poorer carbs than os engines, all idle poorly and build quality isnt quite as good. My lesson learned is to stick with os. Power wise think the 70 will be more than enough, good luck

  8. As a returning flyer i settled on this setup

     

    plywood flying box with cut out for a 12v gel battery and MFA board. Use the MFA board for the glow lead and fuel pump, the MFA board shows glow current which is useful. Used to use the board for a 12v starter as well but realised (as prev comments) that for big (60 2 stroke) motors a geared starter is a must , now use a JustEngines geared starter in a cradle with 3s lipo. Try to keep it simple

  9. Correct, That was the absolute slowest i could get it to run, screwing the low speed idle clockwise, inwards until it cut. 
     

    (12x6 prop, optifuel 12% fuel)

     

    in comparison the os 91 runs at 9600 max revs and will idle slightly slower but definitely a more reliable idle that the sc. 

     

    thanks to all for all the help, i find this incredibly useful, so much to learn

  10. Well ran it on the bench this

    morning and end float issue resolved, only normal float now

     

    spent some time dissling with the low speed idle and could just about get it down to 2800 revs, wot gives 9100.

     

    compression seems fine to answer a prev question. Will give it another chance in a model but wondering if inverted position is a factor. Loathe to use an onboard flow
